Gravitational waves and small-field astrometry
Robin Geyer, Sven Zschocke, Michael Soffel +3
Astrometric observations can, in principle, be used to detect gravitational waves. In this paper we give a practical overview of the gravitational wave effects which can be expecte…

Light propagation in 2PN approximation in the monopole and quadrupole field of a body at rest: The basic transformations
Sven Zschocke
Todays astrometry has reached the micro-arcsecond level in angular measurements of celestial objects. The next generations of astrometric facilities are aiming at the sub-micro-arc…

Light propagation in the 2PN approximation in the monopole and quadrupole field of a body at rest: Boundary value problem
Sven Zschocke
In a recent investigation, the initial value problem of light propagation in the gravitational field of a body at rest with monopole and quadrupole structure has been determined in…
